My boyfriend, who is 30, may have a tendency towards pornography addiction. I'm 28.

My partner and I have been together for over five years. Recently, we bought a home together, and it feels like we're living the married life. Our relationship has always been very intimate; in the early days, we were intimate about four to five times a week, usually two times per session. I know that things can change over time, but the only significant shift in our relationship is that we now live together. We both still have the same jobs and schedules, with no additional stressors that could be affecting his sex drive. However, over the past few months to a year, our intimacy has drastically decreased to maybe twice a month, if I'm lucky. I've talked to him about it, asking if he thinks it could be related to his testosterone levels or if I’ve done something wrong. He insists that it’s not either of those things. I’ve caught him multiple times browsing porn sites and other adult pages, so I know he’s still engaging in self-pleasure. I've jokingly mentioned that he can find time for that but not for us, and he usually just laughs it off, saying we’ll make time tomorrow. I can't help but feel overlooked and unattractive, almost like a toy that has been put away. It’s puzzling to me that he would choose to watch a couple of videos instead of sharing a real intimate experience with me. It really hurts and frustrates me to be in this situation right now. I'm worried that this could be a glimpse of what happens in marriages, or worse, that he might have fallen out of love with me or is interested in someone else (though I believe I would notice that). Normally, I'm good at reading his feelings, but I’m completely lost right now. What should I do?
